Annotated Catalogs (90 in total)

These catalogs are not for sale, but the molecules have biological
activity as reported in the source catalog. EFI and BKS (model systems)
are subsets of Annotated compounds. Purchasable subsets of
annotated catalogs are available as Purchasable Bioactive Compounds or
PBCs.

&nbsp

These databases have been provided to us under collaborative
agreements with each respective catalog owner. Catalogs have been
filtered for drug discovery relevance, and thus compounds in the
original catalog may not be in ZINC. Some documentation on ZINC
subsets is
available.

ZINC may be used free of charge for research by individuals and institutions.
Whereas you are free to share the results of a ZINC search
or a screen of molecules from ZINC, you may not redistribute major
portions of ZINC without the express written permission of
John Irwin.
